Embodiment approach

[0030] Preparation of fluorine-containing cage polysilsesquioxane

[0031] 56.8g heptadecafluorodecyltrimethoxysilane (chemical formula C 8 f 17 CH 2 CH 2 Si(OCH 3 ) 3 ) into 400ml tetrahydrofuran, add 3g sodium hydroxide and 5g deionized water, stir at room temperature for half an hour, raise the temperature to 50±2°C, react for 5 hours, raise the temperature until the reaction system refluxes slightly, and react for 25 hours. The solvent was rotary evaporated until the reaction product became viscous, washed with methanol stored at -5°C, and dried to obtain solid product 1.

[0032] 10g of solid product 1 was added to 300ml of anhydrous tetrahydrofuran, 3g of vinyltrichlorosilane was added, stirred at room temperature for 4 hours, filtered, the filtrate was collected, solvent removed, washed with methanol, and dried to obtain fluorine-containing POSS1 (heptadecafluoro Decyl) vinyl cage polysilsesquioxane).

[0033] 46.8g tridecafluorooctyltrimethoxysilane (chemical fo...

Embodiment 1

[0041] Nitrogen protection was flushed into a closed container, and 99.7g of perfluorohexane diluent, 0.24g of commercially available heptadecafluorodecyltrimethoxysilane and 0.06g of fluorine-containing cage polysilsesquioxane modified silane diluent were successively added. Joint agent 1, stirred and mixed evenly at room temperature to obtain anti-fingerprint oil 1.

Embodiment 2

[0043] Into a closed container under nitrogen protection, add 20g of perfluoroheptane diluent, 0.35g of commercially available heptadecafluorodecyltrimethoxysilane and 0.15g of fluorine-containing cage polysilsesquioxane modified silane coupling Agent 2, stir and mix evenly at room temperature. Anti-fingerprint oil 2 was obtained by adding the remaining 79.5 g of perfluoroheptane diluent just before use.

Abstract

The invention relates to the technical field of anti-oil stain materials, in particular to anti-fingerprint oil, a preparation method, a use method and application. The anti-fingerprint oil is composed of the following raw materials by weight percentage: 99-99.9% of a fluorine-containing diluent and the balance a mixture of a long-chain fluorine-containing silane coupling agent and a fluorine-containing cage type polysilsesquioxane modified silane coupling agent, wherein the long-chain fluorine-containing silane coupling agent accounts for 60-95% of the weight of the mixture, and the fluorine-containing cage type polysilsesquioxane modified silane coupling agent accounts for 15-35% of the weight of the mixture; the chemical structural general formula of the long-chain fluorine-containing silane coupling agent is CF3(CF2)mCH2CH2(CH3)aSi(OM<1>)3-a, the general chemical structural formula of the fluorine-containing cage type polysilsesquioxane modified silane coupling agent is Rf7(SiO1.5)8CH2CH2SCH2CH2CH2(CH3)bSi(OM<2>)3-b. A coating formed after the anti-fingerprint oil is sprayed on a glass product, a ceramic product, a stone material and a metal product and is then dried and curedhas relatively good waterproof, oil-proof, antifouling and anti-fingerprint properties, and is good in smoothness and wear resistance.

Description

technical field [0001] The invention relates to the technical field of anti-oil pollution materials, in particular to anti-fingerprint oil, a preparation method, a use method and an application thereof. Background technique [0002] Anti-fingerprint oil, referred to as AF, is a colorless, odorless, transparent liquid that can be used directly or diluted to a certain concentration and sprayed evenly on the substrate, such as glass cover, mobile phone tempered film, glass screen, etc. After natural drying or heating drying, a layer of nano-scale coating is formed on the surface, which can achieve waterproof, oil-proof, anti-fouling, anti-fingerprint, smooth, wear-resistant and other effects without affecting the visual effect. With the rapid development of touch screen, anti-fingerprint oil is also developing rapidly. [0003] The main material of anti-fingerprint oil is generally a fluorine-containing long-chain alkyl silane coupling agent, combined with a fluorine-containin...
